Credit card drop in component is not loading and gives error

I am trying to add Adyen credit card Drop In component to a web page, but it gives the following error:

Access to fetch at 'https://ift.tt/2S1AWOp' from origin 'https://ift.tt/3ioRAls' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource. If an opaque response serves your needs, set the request's mode to 'no-cors' to fetch the resource with CORS disabled.
